Tavern is made by wbmc
This is a very nice concept. A little wordly, maybe some trait, like:
* Building: +2 attack, countdown reduced by 1.
At the beginning of each turn, the creature on Taverns tile is healed by 2.
Where Building trait reads: "Any creature can occupy the tile this structure is on. When its countdown reaches 0, an effect is applied to the creature on this building."
Ya, using traits would be way better, but you can't create custom traits in the designer unfortunatly.
